Gestational diabetes is a multifactorial disease that increases the risk for complications for the mother and her child in the short and long term. The perinatal period represents an opportunity not only to assist the mother in improving her own health but also that of the future generation. This article focuses on lifestyle and psychological aspects that form the base for non-medical treatment approaches. Considering different risk factors separately is not sufficient for the improvement of the metabolic and mental health of women with gestational diabetes. With a multimodal interdisciplinary approach that includes physical activity, dietary advice and psychological support, an improvement of the health and well-being of both the mother and her child is expected. Future studies are necessary to confirm this proposed care approach.
